Clade 2.3.4.4b of the highly pathogenic avian influenza (HPAI) virus causing outbreaks in wild and domestic birds around the world, continues to spread in dairy cows, poultry and other animals across the United States.

Together with Meral Akcay, Lucy Mosscrop and Marco Goeijenbier we’ll delve into their unique journeys, the challenges they face, and the advice they offer to those just starting out in science.

Scientists find evidence of past H5N1 infection in 7% of workers exposed at dairy farms—but no signs of human-to-human transmission

Consistent H5N1 control needed for farm animals

A three-part series focusing on essential vaccination practices. It covers key aspects such as understanding vaccine protocols, ensuring proper documentation and record-keeping, and effective communication with patients.

Highlights from the scanning surveillance network

In April 2024, an unprecedented outbreak of highly pathogenic avian influenza (HPAI) H5N1 virus, which belongs to HA clade 2.3.4.4 b, was reported in dairy cattle and related milk products in the US.

Since 2020, there has been unprecedented global spread of highly pathogenic avian influenza A(H5N1) in wild bird populations with spillover into a variety of mammalian species and sporadically humans.

The outbreak of clade 2.3.4.4b highly pathogenic avian influenza viruses of the H5N1 subtype (HPAI H5N1) in dairy cows in the US has so far resulted in spillover infections of at least thirteen farm workers.

Patients suffering from post-COVID syndrome generally feel supported by their general practitioners; they take their complaints seriously and actively collaborate on finding solutions.

The case of avian influenza A (H5) confirmed by the Centers for Disease Control and Prevention in Missouri, USA.

Held annually in October, this campaign aims to raise awareness of the importance of vaccination for people’s health and well-being and to increase the uptake of seasonal influenza vaccination of people with underlying risk factors.
